I just finished Scorn, it was very interesting.

I feel like the combat wasn't necessary since the puzzles and exploration felt like the main focus of the game, but at the same time, I don't know how they could have made the environment feel dangerous without the threat of death. There was a puzzle later in the game that did require you to injure yourself, but I don't think that would have worked as a replacement for combat in the rest of the game, and being present throughout the game would lessen the impact of it in the short moment where it is actually necessary. Also, the guns were very neat looking, so that is an additional upside to having combat.

Even though this sounds like a lot of complaining, I don't think I could come up with any other criticisms, as pretty much everything else about the game felt perfect. I don't think it is the sort of thing I will play again, but it will be something I will think back on more than most other games.
